Ground Flat Stock
Subject to size suitability and availability pieces can be produced as ground flat stock in approximately 3 to 4 weeks. Standard and non-standard sizes can be made.
Forging
Heat the steel slowly and uniformly to 700°C then more rapidly to 900-1040°C. After forging slow cool.
Annealing
X153CrMoV12 is supplied in the annealed and machineable condition. Re-annealing will only be necessary if the steel has been forged or hardened. To anneal, heat slowly and uniformly to 900°C. Soak for three to four hours and then allow to cool in the furnace. Re-heat to 800-1040°C and again soak for three to four hours. Allow to cool in the furnace.
Stress Relieving
If heavily machined, ground or otherwise subjected to cold work, the relief of internal strains is advisable before hardening to minimise the possibility of distortion. Stress relieving should be carried out after rough machining. To stress relieve, heat the steel to 600-650°C. Soak well and cool in the furnace or in air.
Hardening
It is preferable to heat the tools in a controlled atmosphere. If this is not possible, pack hardening is recommended. A reducing atmosphere is desirable. Pre heat X153CrMoV12 steel to 750-800°C. and allow to soak at this temperature. The temperature should then be brought up to 1000-1040°C for air cooling, or 980°C for oil quenching. Soak thoroughly at temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly.
